Voice benchmark evidence
Gemini 3.8 TTS launch evaluation is an owner-defined voice evaluation. Its result stays separate from BenchLM's weighted text-model ranking.
Lineage
The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Gemini 3.8 Flash-Lite TTS, but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.
Gemini 3.8 Flash-Lite TTS is a proprietary model with a 8K context window. No explicit reasoning mode is documented in this profile.
Released September 23, 2026 as the stable `gemini-3.8-flash-lite-tts` model in the Gemini API and Google AI Studio, with Google Vids access rolling out. Google documents 8,192 text input tokens, audio output, 101 supported languages, voice design and replication, and SynthID watermarking. Gemini Enterprise API access is planned, not yet available.
Gemini 3.8 Flash-Lite TTS is a display-only text-to-speech model for high-volume generation and voice-agent cascades. Its voice results remain separate from weighted text-model scores.
Gemini 3.8 Flash-Lite TTS sits in the Gemini 3.8 TTS family with Gemini 3.8 Flash TTS. Its explicit predecessor is Gemini 3.1 Flash TTS Preview. Speech or voice evidence appears above; text-model benchmark coverage remains empty.

Questions
How does Gemini 3.8 Flash-Lite TTS perform overall in AI benchmarks?
Gemini 3.8 Flash-Lite TTS has published speech or voice results in Gemini 3.8 TTS launch evaluation. Those results remain separate from the weighted text-model ranking, so this profile does not assign a BenchLM score or overall rank. Use the linked evaluation's metric and run conditions to compare speech systems.
Which sibling models are related to Gemini 3.8 Flash-Lite TTS?
Gemini 3.8 Flash-Lite TTS belongs to the Gemini 3.8 TTS family. Related tracked variants include Gemini 3.8 Flash TTS. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does Gemini 3.8 Flash-Lite TTS have full benchmark coverage on BenchLM?
No. Gemini 3.8 Flash-Lite TTS's speech or voice results appear in Gemini 3.8 TTS launch evaluation, but it has no published text-model benchmark rows. The voice evaluation does not fill the text-model coverage slots or produce an overall rank. Missing text coverage is not treated as a zero score.
What is the context window size of Gemini 3.8 Flash-Lite TTS?
Gemini 3.8 Flash-Lite TTS has a documented context window of 8K. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
